You can also find these digits using the Three app or in your phone’s settings. Here’s how:

Note: If you’re using a version of our app that doesn’t give you your ICCID, Google Play has many free apps that will find yours for you. You can find them by searching for ‘ICCID’ in the Google Play store.
